3. Configure MD5 authentication
Before configuring MD5 authentication
Unilaterally configure MD5 authentication on R1
R1 (config) # router bgp 1
R1 (config-router) # neighbor 12.1.1.2 password cisco
MD5 authentication is also configured on R2
R2 (config) # router bgp 2
R2 (config-router) # neighbor 12.1.1.1 password cisco
